Sunex SX300 Mini Right Angle & Straight Die Grinder Combo

[This review was collected as part of a promotion.] Performance of these die grinders is great! Using the recommended air pressure and hose diameters has a noticeable effect on the speed so I'd go by what the manual says. Used to get the rust off of some stock welding material and they worked extremely well not bogging down at all. The feel is good in the hand. The threads were a little tight on mine and for a second I thought that they weren't NPT but they are. I'm not sure I like that the collar on the body is made of plastic and was loose on mine. My concern is it cracking if ever i put a wrench on it. The controls are good for throttling the tool to control speed. All in all a great tool.

[This review was collected as part of a promotion.] I got these recently, and I've been able to put them through a little bit of use. Overall, I'm impressed with the quality of the grinders. They have easily handled the projects I've thrown at them, using carbide bits to do some metal grinding. I was originally shopping for a single grinder, but I appreciate having the versatility of having both a straight grinder and an angled grinder when the need arises - sometimes, you just need that extra space to reach what you want to work on. The grinders are compact and lightweight, making them easy to use and maneuver. I'd highly recommend this set.
